Dynamic Forcing Function for Flow-Acoustic-Induced Vibration
(The American Society of Mechanical Engineers (ASME), 1989)Vibration problems in piping systems can manifest themselves in two forms: excessive noise generated from wall flexural vibrations, that in combination with jet noise itself may exceed OSHA ... -
Design, Assembly, and Inspection of Advanced U-Bend/Antivibration Bar Configurations for PWR Steam Generators
(The American Society of Mechanical Engineers (ASME), 1989)Tube vibration and wear potential in the U-bend region of pressurized water reactor (PWR) steam generators is reduced by enhanced design bases and fabrication procedures. Applicable vibration ... -
Simulation of Tube-to-Support Dynamic Interaction in Heat Exchange Equipment
(The American Society of Mechanical Engineers (ASME), 1989)Tubes within tube and shell heat exchange components are supported at intermediate points by support plates. Flow-induced vibration of a tube can cause it to impact or rub against a support ... -
The Temperature Field for Simulating Partial Autofrettage in an Elasto-Plastic Thick-Walled Cylinder

Stress Analysis of Pressure Vessels With Uniformly Spaced Lugs
(The American Society of Mechanical Engineers (ASME), 1988)Stresses and displacements in circular cylindrical shells having square and rectangular lugs have been studied in this paper. The analysis presented here is based on finite element technique ... -
The Effect of Flaw Shape on the Fracture Propensity of Nozzle Corner Flaws
(The American Society of Mechanical Engineers (ASME), 1988)Three-dimensional finite element models were formulated to evaluate the distribution of the elastic stress intensity factor around the periphery of cracklike flaws postulated to exist at the ... -
Shell Solution for Reinforced Cylinder to Sphere Intersection
(The American Society of Mechanical Engineers (ASME), 1988)To reduce the stress level at nozzle to spherical pressure vessel intersections, reinforcement is generally added to the sphere, the nozzle or both. This paper describes the development of a ... -
An Effective Method of Analyzing Rocking Motion for Unanchored Cylindrical Tanks Including Uplift
(The American Society of Mechanical Engineers (ASME), 1988)In order to calculate the rocking response of the unanchored cylindrical tank, including the bottom uplift due to seismic loading, a simple but effective method is developed. Firstly, an analysis ... -
Plastic Work Interaction Damage Rule Applied to Narrow-Band Gaussian Random Stress Situations
(The American Society of Mechanical Engineers (ASME), 1988)Fatigue life estimates that use a structural material’s constant amplitude stress life data values and a linear cumulative damage rule are always nonconservative for stress histories containing ... -
Statistical Forecasting of Trends in Tubular Pressure Part Forced Outage Rates for Fossil Boilers
(The American Society of Mechanical Engineers (ASME), 1988)Statistical models for calculating age-dependent component failure rates and system unavailabilities have been combined into a flexible procedure to forecast trends in tubular pressure part forced ... -
Numerical Evaluation of Two Creep-Fatigue Damage Models Under Complex Loading Histories and Multiaxial States of Stress
(The American Society of Mechanical Engineers (ASME), 1988)The work is focused on the modeling of creep-fatigue behavior in austenitic stainless steels in the presence of complex loading histories and multiaxial states of stress. Two interaction models, ... -

Creep Crack Initiation and Propagation: Fracture Mechanics and Local Approach
(The American Society of Mechanical Engineers (ASME), 1988)Both the initiation and the propagation of macroscopic creep cracks have been studied in 316-L austenitic stainless steel, and, for comparison purposes, in 2219-T851 aluminum alloy. These alloys ... -
Constitutive Modeling of 17-12 Mo SPH Stainless Steel Behavior at High Temperature
(The American Society of Mechanical Engineers (ASME), 1988)A systematic comparison of the detailed behaviors predicted by current constitutive models under various loadings and the actual behavior of austenitic steels under the same lodings was carried ... -
Viscous Flow Structure Interaction
(The American Society of Mechanical Engineers (ASME), 1988)Considerable research activities in vibration and seismic analysis for various fluid-structure systems have been carried out in the past two decades. Most of the approaches are formulated within ... -
Experimental Determination of Single and Two-Phase Cross Flow-Induced Forces on Tube Rows
(The American Society of Mechanical Engineers (ASME), 1988)The fluctuating forces induced by water and air/water cross flow on tube rows with pitch to diameter ratios of 1.5 and 3 were measured. Direct measurement of force spectra was possible because ... -
Experimental Investigation of Dynamic Parameters of Viscous Fluids in Unsteady Flow
(The American Society of Mechanical Engineers (ASME), 1988)The main objective of this paper is to conduct a series of experimental investigations to measure the effective mass moment of inertia and damping coefficient of a viscous fluid due to an ... -
A Total Strain Energy Density Theory for Cumulative Fatigue Damage
(The American Society of Mechanical Engineers (ASME), 1988)A unified theory based on the cyclic strain energy density criterion is presented first. It is shown that the fatigue failure in both low and high-cycle regimes, and cumulative damage and ... -
Stress and Strength Analysis of Concentric Reducers Consisting of Plates
(The American Society of Mechanical Engineers (ASME), 1988)This paper presents a new kind of piping component—a concentric reducer consisting of plates. Authors performed experimental and elastic, elastic-plastic analyses on five test models having different ...
